Description

Insecticidal lamp short-circuit prevention type power grid and insecticidal lamp with same

Technical Field

The invention relates to the technical field of insecticidal lamp power grids, in particular to an insecticidal lamp short-circuit-preventing power grid and an insecticidal lamp with the power grid.

Background

The traditional agricultural and forestry disinfestation mode is often to spray pesticides on plants, but the pesticides can remain on crops and have a certain threat to human health. With the continuous development of modern agriculture and the gradual increase of requirements for ecological environment protection, in recent years, insecticidal lamps are widely used in insecticidal. The use of the insecticidal lamp can reduce the dependence on pesticides to a great extent, and the insecticidal lamp has better insecticidal capability and can kill most agricultural and forestry pests.

With the continuous development of the insecticidal technology, the technical requirements on the tools used for killing and removing insects are also higher and higher. In the known technology, the frequency vibration type insecticidal lamp has wide insecticidal variety and can trap and kill various vegetable pests. The pest killing mechanism of the frequency vibration type pest killing lamp is to use four trapping modes of sound, wave, color and smell to kill pests, short-distance light and long-distance wave are used, and yellow light source and sex information are used for trapping and killing pests. The high-voltage power grid is arranged around the insect-guiding lamp, and when pests touch the high-voltage power grid in the process of flying to the lamp tube under the induction of the insect-guiding lamp, the pests are electrocuted or stunned by the high-voltage power grid, so that the insect killing effect is realized.

The traditional cylinder type insecticidal lamp has the advantages that the high-voltage grid is distributed in a radial mode by taking the insecticidal lamp as the center, insect pests are stacked on the high-voltage grid after being electrocuted, the insect pests can not shade the insect guiding lamp, but the insecticidal rate of the insecticidal lamp is low, and the insect pests fly away easily. When the air is gradually cooled, pests are reduced, and the traditional cylindrical insecticidal lamp is used for insecticidal operation, energy waste can be caused.

The traditional light trap pest-killing lamp has no self-cleaning function, if the lamp is installed in mountain areas or remote areas, pest bodies adhered to a high-voltage power grid cannot be cleaned every day, a plurality of pest bodies are adhered to the high-voltage power grid over time, when the pest-killing lamp works again, the pest bodies form conductors, two extremely short circuits of the high-voltage power grid are directly caused to form arc discharge, and the pest bodies are spontaneously burned by strong current, so that the risk of fire is caused.

The existing insecticidal lamp lacks a cleaning mechanism for electrode wires, so that the insecticidal effect is unstable in the insecticidal process. Namely, after the insect is shocked, the produced keratinized matter can adhere to the electrode wire, and if the keratinized matter cannot be cleaned off the electrode wire in time because the keratinized matter has an insulating effect, the electrode wire at the corresponding part can be insulated along with the continuous thickening of the horny layer, the insecticidal function is lost, and the insecticidal effect is affected.

The existing frequency vibration type insecticidal lamp mainly comprises an insecticidal lamp main body, an insect-inducing electric lamp, a storage battery, a monocrystalline or polycrystalline photovoltaic component, a high-voltage generator, an electric appliance controller, an insecticidal power grid and the like. However, due to the limitation of the structure, the insect killing effect is seriously affected after the insect bodies are stuck on the high-voltage net, and if the insect bodies are not cleaned in time, the serious result of burning the whole lamp caused by spontaneous combustion of the insect bodies is also caused. Although various cleaning mechanisms are arranged on the power grid for the insect bodies, the insect bodies are limited by the overall structure, the cleaning thoroughness of the insect bodies is particularly easy to cause the accumulated problem of the insect bodies, and the risk of burning of the insect killing lamp body caused by certain short circuit conduction still exists.

Detailed Description

The structures, proportions, sizes, etc. shown in the drawings are shown only in connection with the disclosure of the present invention, and are not intended to limit the scope of the invention, which is defined by the claims, but rather by the terms of modification, variation of proportions, or adjustment of sizes, without affecting the efficacy or achievement of the present invention, should be understood as falling within the scope of the present invention. Also, the terms such as "upper", "lower", "front", "rear", "middle", and the like are used herein for descriptive purposes only and are not intended to limit the scope of the invention for which the invention may be practiced or for which the relative relationships may be altered or modified without materially altering the technical context.

The utility model provides a insecticidal lamp prevents short circuit electric wire netting as shown in fig. 1 to 3, prevent short circuit electric wire netting by many longitudinal arrangement's wire electrode A1, wire electrode B2 and transversely set up and correspond two grid-connected wire electrode A11 of wire electrode A1 upper and lower both ends, transversely set up and correspond two grid-connected wire electrode B21 of wire electrode B2 upper and lower both ends. And the grid-connected electrode wires A11 and B21 correspondingly connect the electrode wires A1 and B2 into an integral net structure. After the electrode wires A1 and B2 are connected into a whole net structure, the electrode wires A1 and B2 are staggered to form a planar power grid (shown in figure 3). In the case shown in fig. 1 and 3, after the wire electrode A1 and the wire electrode B2 are connected to form a planar grid, the axes of the wire electrode A1 and the wire electrode B2 are located in the same plane. As an optimization scheme, a certain interval is formed between the plane of the axis of the electrode wire A1 and the plane of the axis of the electrode wire B2 in the radial direction (the left and right directions are shown in the figure 2), and the interval is in the range of 0 < "interval value". Ltoreq.1/2 radius of the electrode wire B (the diameters of the electrode wire A1 and the electrode wire B are consistent).

When the plane where the axis of the electrode wire A1 is located is opposite to the plane where the axis of the electrode wire B2 is located, a certain distance is formed between the planes in the radial direction, so that the structure of the power grid can be further improved. At this time, the cleaned insect bodies are not easy to clamp between the adjacent electrode wires A1 and B2, and at this time, because of the dislocation difference between the adjacent electrode wires A1 and B2, the area of the corresponding surface (the corresponding surface seen from the view direction shown in FIG. 4) is reduced, and the clamping force between the adjacent electrode wires A1 and B2 is greatly weakened due to the cylindrical influence of the electrode wires A1 and B2, so that the accumulated insect bodies are not easy to clamp, and the individual large insect bodies are not easy to clamp between the adjacent electrode wires A1 and B2 after being electrified. Therefore, the normal operation of the power grid can be ensured. In addition, under the above configuration relation, the two electrode wires can not touch the positive electrode wire and the negative electrode wire simultaneously when flying insects impact the power grid due to the small diameter size of the electrode wires.

It should be noted that, the phrase "the wire electrode A1 and the wire electrode B2 are staggered to form a planar grid" is understood to include a case where a plane in which an axis of the wire electrode A1 is coincident with a plane in which an axis of the wire electrode B2 is located and a case where a certain distance exists in a radial direction with respect to a plane in which an axis of the wire electrode A1 is located.

When the electrode wire A1 and the electrode wire B2 are automatically cleaned from top to bottom through the cleaning device, insect bodies can fall off from the lower ends of the high-voltage grid formed by the electrode wires A1 and the electrode wires B2 in a staggered mode and finally fall out from the insect leakage holes 31 on the chassis 3, the insect bodies basically cannot be accumulated at the lower ends of the high-voltage grid, the cleaning effect is improved, the high-voltage grid can keep long-time efficient insecticidal capability, and the risk of fire occurrence is reduced.

The upper end and the lower end of the electrode wire A1 with the same polarity are respectively bent outwards and obliquely arranged, so that the insect corpse can fall off from the electrode wires (the electrode wire A1 and the electrode wire B2) when the electrode wire A1 and the electrode wire B2 are cleaned by the cleaning device, and the insect corpse is prevented from being accumulated at the upper end and the lower end of the high-voltage grid formed by the electrode wires.

As shown in fig. 1 to 4, each of the upper and lower portions of the wire electrode A1 has a section bent outward, the bending point of the lower section is located above the lower end of the wire electrode B2 (preferably, the vertical pitch value is not less than 2 cm), and the bending point of the upper section is located below the upper end of the wire electrode B2 (preferably, the vertical pitch value is not less than 2 cm). The upper end of the electrode wire A1 is provided with a guide connection support foot A111, and the lower end is provided with a support foot A112. The upper end of the electrode wire B2 is provided with a guide connection support leg B211, and the lower end is provided with a support leg B212.

In order to prevent the conduction branch pin A111, the support pin A112, the conduction branch pin B211 and the support pin B212 from obstructing the up-and-down action of a power grid cleaning mechanism arranged in the insecticidal lamp, and simultaneously in order to ensure the simplicity of the structure, the processing and the forming are convenient, in particular: a connecting support leg A111 is arranged on one grid-connected electrode wire A11 which is connected to the upper end of the electrode wire A1, a support leg A112 is arranged on one grid-connected electrode wire A11 at the lower end, and the connecting support leg A111 and the support leg A112 are preferably arranged at two end parts of the corresponding grid-connected electrode wire A11; a connecting support B211 is arranged on one grid-connected electrode wire B21 which is connected with the upper end of the electrode wire B2, a support B212 is arranged on one grid-connected electrode wire B21 at the lower end, and the connecting support B211 and the support B212 are preferably arranged at two ends of the corresponding grid-connected electrode wire B21.

In order to insulate the lower end of the short-circuit-preventing power grid from the chassis, insulation caps are sleeved on the support legs A112 and B212. Preferably, the insulating cap is a ceramic end cap. As shown in fig. 8, a plurality of sets of piles 34 (four piles are distributed on the chassis 3), the piles 34 are used to fix the support legs a 112 and B212 in the short-circuit-preventing grid, and finally, the position of the planar net composed of the wire electrode A1 and the grid-connected wire electrode a 11 is relatively fixed to the position of the planar net composed of the wire electrode B2 and the grid-connected wire electrode B21, and of course, the planar net is completely fixed by matching with the top cover of the insecticidal lamp by means of the guide legs a 111 and the guide legs B211.

After the ceramic end caps are arranged on the support leg A112 and the support leg B212, the support leg A112 and the support leg B212 are arranged in the pile 34 (the ceramic end caps are fully wrapped on the outer leakage parts of the support leg A112 and the support leg B212, so that excessive insect bodies or sticky body fluid exuded after electric shock of the insect bodies can be avoided, and when the insect leakage holes 31 on the chassis 3 cannot smoothly fall down, short circuits are caused between the support leg A112 and the support leg B212 along with the continuous increase of accumulated quantity, and fire disaster is caused. The risk of burning of the insecticidal lamp body caused by short circuit can be further reduced.

An insecticidal lamp based on the above-mentioned short-circuit prevention type power grid, as shown in fig. 4, comprises three groups of short-circuit prevention type power grids. Each group of short-circuit prevention power grids are fixed on the upper end face of the chassis 3 of the insecticidal lamp through a support leg A112 and a support leg B212 which are arranged at the lower part, and a guide connection support leg A111 and a guide connection support leg B211 which are arranged at the upper part extend into a top cover of the insecticidal lamp to be respectively connected with positive and negative electrodes of a power supply. Three groups of short-circuit prevention power grids are arranged around the outside of the worm leakage hole 31 in the center of the chassis 3 of the insecticidal lamp in a surrounding manner in the circumferential direction. Specifically, the three groups of short-circuit prevention grids are surrounded on the outer side of a circle I concentric with the worm leakage hole 31 (the diameter of the circle I is larger than that of the worm leakage hole 31), projection extension lines of grid-connected electrode wires B21 in the groups of short-circuit prevention grids on the chassis 3 are respectively circumscribed with the circle I, and central angles between adjacent tangent points are alpha (alpha value is 120 degrees). The three groups of short-circuit prevention power grids arranged at this time form a spiral shape on the chassis 3 (the width extension direction of each group of short-circuit prevention power grids is parallel to the radial direction of the center of the chassis 3), and compared with the form that the width of each group of short-circuit prevention power grids is arranged along the radial direction of the center of the chassis 3, the three groups of short-circuit prevention power grids are beneficial to increasing the area of the power grids, so that the insect catching amount is improved. In addition, the spiral arrangement form can induce the flying insects, so that the flying insects which are not hit at the periphery are continuously attracted to fly to the inner end (the end close to the center of the chassis 3) of the power grid, and finally killed, and the insect catching effect is improved.

When the short-circuit preventing power grids are arranged into three groups, the three groups of short-circuit preventing power grids can surround the outer side of the worm leakage hole 31 and are circumferentially arranged in a Y shape (the width extension direction of the short-circuit preventing power grids passes through the radial direction of the center of the chassis 3). The short-circuit prevention power grids can also be arranged into four groups, and the four groups of short-circuit prevention power grids are arranged around the outer side of the worm leakage hole 31 in an X-shaped or cross-shaped manner in a surrounding manner in the circumferential direction. That is, at this time, three or four high-voltage grids of each group consisting of the electrode wire A1 and the electrode wire B2 are radially arranged outwards around the axis of the chassis 3, and the included angles between two adjacent high-voltage grids can be 90 ° (in the cross shape) or 120 ° (in the Y shape), or can be in a form (in the X shape) of alternating two groups of 120 ° -60 ° -angles, so that the flying pests in all directions can be effectively killed, the pests can be killed in all directions, and the pest killing effect can be improved.

As shown in fig. 5 to 7, the insecticidal lamp further comprises a grid cleaning mechanism 4 and a mounting seat 33 arranged above the weeping hole 31.

As shown in fig. 7 and 8, the mount 33 includes a leg connected to the chassis 3 and a circular truncated cone provided on an upper portion of the leg. The lower ends of the supporting legs are connected to the periphery of the worm leakage holes 31. The circular truncated cone upper end surface is provided with a shaft hole 332.

As shown in fig. 5-7, the power grid cleaning mechanism 4 includes a driving disc 41 and three supporting arms 42:

one end of each supporting arm 42 is connected to the outer peripheral surface of the driving disc 41, and is tangent to the same axis, so that the arrangement direction of each supporting arm 42 is finally in one-to-one correspondence with each group of short-circuit preventing power grids shown in fig. 4 (the final matching structure is shown in fig. 7). At the other ends of the support arms 42, claws 421 are provided, respectively.

On the other side of the support arm 42 facing away from the tangent of the support arm 42 to the drive disk 41, cylindrical cleaning teeth 43 are arranged, the axial direction of the cleaning teeth 43 extending perpendicularly relative to the other side.

The cleaning teeth 43 are respectively disposed between the adjacent electrode wires A1 and B2, as shown in fig. 6 and 7. The cleaning teeth 43 are ceramic teeth to provide good insulation and sufficient strength and wear resistance.

A screw hole 411 is provided in the drive disk 41 in the axial direction, and a screw is disposed in the screw hole 411. The lower end of the screw rod is assembled in the shaft hole 332 of the assembling seat 33, the upper end of the screw rod penetrates into the top cover of the insecticidal lamp to be matched with the motor, and the motor is connected with the controller. The controller can control the starting of the motor at regular time and the forward and reverse rotation condition of the motor during each starting.

Between the chassis 3 and the top cover, the claws 421 at the ends of the supporting arms 42 are arranged in a one-to-one correspondence, and guide posts extending in the vertical direction are fixedly arranged. As shown in fig. 4, 7 and 8, a mounting post 32 is provided on the chassis 3 to be connected to the lower end of the guide post. After assembly, the corresponding guide posts are wrapped by the arc-shaped clamping grooves formed in the clamping claws 421. The screw drives the driving disk 41 to move up and down under the driving of the motor, and the claw 421 slides along the outer wall of the guide post.

As shown in fig. 9, a bearing cap 331 is assembled at the upper end of the shaft hole 332, and three limiting posts 3311 are uniformly distributed on the upper end surface of the bearing cap 331 along the circumferential direction, and the axial direction of the limiting posts 3311 extends upwards along the vertical direction. The upper end of the limiting post 3311 contacts with the lower end plane of the driving disc 41 when the driving disc 41 moves downwards to the lower part, and the downward displacement of the driving disc 41 is limited, so that the phenomenon that the driving disc 41 is excessively displaced downwards, is blocked and cannot be moved upwards for resetting can be avoided.

As an extension, the bearing cover of the structure can be arranged on the top cover of the insecticidal lamp, and the limiting post axially extends downwards at the moment to avoid the blocking at the top part when the driving disc 41 moves upwards, so that the movement can not be moved downwards.

In summary, the power grid structure with the short-circuit prevention function and the insecticidal lamp with the power grid can effectively drain the insect bodies cleaned by the electrode wires and finally collect the insect bodies on the chassis, and can prevent the insect bodies cleaned from accumulating at the upper end and the lower end of the power grid to a great extent to cause short circuit and cause the combustion of the insecticidal lamp body. Therefore, the invention effectively overcomes some practical problems in the prior art, thereby having high utilization value and use significance.
